Where does your AI data actually live in 2026?

When you call a hosted LLM, your text crosses your network, the provider's edge and an inference region, and many providers do not document where inference runs. Residency options range from a global API to in-region cloud, private endpoints and fully on-prem or air-gapped deployment. Plugsky offers region-locked data planes in the EU, GCC, APAC and US.

Key facts

In-region cloudYour chosen region (EU, GCC, APAC, US) for data localisation requirements
Private endpointRuns in your VPC for isolation plus managed models
On-premYour data centre; air-gapped and classified workloads
GCC coverageme-central-1 and sa-central-1 data planes with Arabic-first models
EncryptionTLS 1.3 in transit, AES-256 at rest, customer-managed keys available
AuditPer-request logs, SIEM export, retention configurable up to 7 years on Enterprise

TL;DR

  • Ask every provider where inference runs, and get the answer in writing.
  • Most workloads do not need residency; identify the ones that genuinely do.
  • Route sensitive traffic to a residency tier and everything else to the cheaper tier.
  • Open-weight models can run in-region or on-prem, so data never leaves.
  • Re-check residency quarterly: providers change infrastructure without notice.

How it works, step by step

  1. Inventory data classes: prompts, completions, embeddings, logs and fine-tuning data.
  2. Ask each provider to document inference and storage regions in writing.
  3. Map workloads to the minimum residency tier each one requires.
  4. Configure region selection and customer-managed keys where available.
  5. Verify that audit logs and retention match your regulator's expectations.
  6. Schedule a quarterly re-check of subprocessors and regions.

The reality of data flows

When you call a hosted LLM API, your text crosses your network, the provider's edge and their inference region. Many providers do not document where inference runs, which is the actual risk for regulated industries, not the data itself.

Residency is therefore a documentation problem before it is an infrastructure problem. If a provider cannot tell you, in writing, where prompts, completions, embeddings and logs are processed and stored, you cannot assess the transfer.

Your residency options

Options range from a global API with provider-chosen regions (fine for prototyping and non-sensitive data) to in-region cloud (EU, GCC, APAC or US) for data localisation requirements, a private endpoint inside your VPC for isolation with managed models, and on-prem or air-gapped deployment for classified workloads.

Cost and operational burden rise as you move down that list, so map each workload to the minimum tier it actually requires. Most workloads do not need the strictest option; the sensitive minority usually does.

The Gulf angle and a practical checklist

Gulf regulators are moving toward data localisation expectations, and Arabic-language AI adds a second requirement: models that work in Arabic. A GCC-hosted platform with Arabic-first models addresses both, so data stays home and the models speak the language.

Practical checklist: ask every provider where inference runs, in writing; identify which workloads genuinely need residency; route sensitive traffic to the residency tier and the rest to the cheaper tier; and re-check quarterly, because providers change infrastructure without notice. Read the data residency guide for control-by-control detail.

The same OpenAI-compatible API exposes 30+ models in-region, so residency does not force you into a single small model.

Frequently asked questions

Does residency hurt quality or latency?

In-region hosting can improve latency for local users and has no quality impact on open-weight models. The model itself does not change with the region.

What about the model vendor?

Open-weight models run anywhere, so there is no vendor API that receives your data. That is the core of sovereign AI.

Which regions does Plugsky support?

EU (Frankfurt), GCC (UAE and KSA), APAC (Singapore) and US (Virginia and Oregon) residency options, with data planes locked to the selected region.

Can I use customer-managed keys?

Yes. Plugsky supports BYOK with AWS KMS, Azure Key Vault, HashiCorp Vault and on-prem HSM, plus an optional zero-knowledge mode.

How do I prove residency to an auditor?

Use per-request audit logs, the DPA and subprocessor list, right-to-audit clauses and SOC 2 Type II reports under NDA.

Do embeddings and vector stores stay in region?

Yes. Embeddings, RAG collections and their storage stay in the residency you select, and Enterprise can run them inside your own VPC.
